IMPROVEMENT IN HORSESHQES.

Specification forming part of Letters Patent No. 157,179, dated November24, 1874; application filed September 4, 1874.

To all whom it may concern:

Be it known that I, JAnEs J OBEY, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new Improvement inHorseshoes; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1., an under-side view of a shoe, the the toe-ealk attached, ashort calk at one heel, and the other heel as ready to receive the calk;Fig. 2, section on line as or; and in Fig. 3, perspective View of thecalk.

This invention relates to an improvement in the construction ofhorseshoes and the attachment of calks thereto, the object being tofirmly attach the calks, and yet allow of their removal and replacementby new calks when occasion requires; and it consists in a shoeperforated at the points where the calks are to be attached, the undersurface around the said perforation being hardened sothat they form diesinto which pins or studs on the under side of the calks are driven orforced, the said dies dressing the said studs, so that they becomeself-fittin g, as more fully hereinafter described.

A is the shoe in outline, substantially like the usual construction. Atthe heels and toe the under surface is faced with a plate, a, of steel,hardened as for dies or the shoe may be made entirely of a metal, thesurface of which at the heels and toe is capable of being hardened tothe required degree. At these points the shoe is perforated with twoholes, d, (one will answer;) but the surface or edge around theseperforations upon the under side of the shoe must be clean out andsharp; B, the calk, is constructed with studs 1) upon the under side,corresponding to but slightlylarger than the said perforation. The calkis then placed over the perforations and forced down until the studs areset into their place, as seen in Fig. 2. The die or hardened edge of theperforations dress the studs as they pass in, and thus perfectly fit thecalk to the shoe, and in such manner that great force is required toremove the calk.

In order to remove the calks when they are worn, or for any causerequire removal, I form a channel, f, across the surface between thestuds, as seen in Figs. 2 and 3, into which a wedge may be driven toforce the calk from the shoe.

By this construction, the calks are practically self-fitted, and inplacing or replacing the caks the shoe is not liable to injury, but willordinarily outlast several sets of calks.

At one heel a short calk with one stud only is shown. In some cases thiswill be sufficient for that position.

I claim A horseshoe, A, with perforations d, to receive the calks, andthe surface around said perforations hardened, as described, combinedwith the calks B, constructed with stud or studs 12, substantially asspecified.
